Monoclonal antibodies (mAbs) are widely used in cancer therapy and recently many new mAbs have gained EMA and FDA approvals for oncology indications. Here we describe a highly reproducible CZE method, relying on a cationic coating allowing separation and identification of a complex mixture of four compounded mAbs widely used in cancer therapy (cetuximab, rituximab, bevacizumab, and trastuzumab).
